Nikon has announced a firmware update for its new AF-S NIKKOR 300mm f/4E PF ED VR, to fix an issue where at certain shutter speeds on D800-series cameras, images can exhibit ‘noticeable blur’. According to Nikon, the problem can occur at around 1/125sec with the lens’s VR function enabled in either ‘Normal’ or ‘Sport’ modes. Users of affected units (those with serial numbers lower than 205101) are encouraged to return their lenses to Nikon where the update will be applied free of charge.

Nikon has confirmed that when the AF-S NIKKOR 300mm f/4E PF ED VR lens is used with the D800, D800E, D810 or D810A, images captured at shutter speeds of around 1/125 s with the VR function enabled (NORMAL or SPORT) sometimes exhibit noticeable blur.

To address the occurrence of this, we are offering a service for updating your AF-S NIKKOR 300mm f/4E PF ED VR firmware.

When cameras other than the D800, D800E, D810, or D810A are used, this firmware update is not needed.

Users of the D800, D800E, D810, or D810A who are concerned about this issue may take or send their lens to a Nikon authorized service center, where your lens firmware will be updated free of charge.

When sending your AF-S Nikkor 300mm f/4 E PF ED VR lens to a Nikon authorized service center, the user must pay the cost of shipping to the service center, and Nikon will pay for return shipping.

Firmware for lenses with a serial number of 205101 or later has already been updated.
